All:
Regarding kern/38260, a patch that improves carp(4) event debugging logs:
My co-worker has published an updated patch that applies cleanly to
-current and netbsd-5.
http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=38260
We've worked with OpenBSD/FreeBSD to accept very similar patches. We
believe this to be ready to be reviewed & commited.
Thanks, ~BAS

Hmm, could you diff -u it? the diff is hard to read. I would apply it
and see the diff myself but don't have a machine at hand. But I'll look
at it for you.
